If you're reading this, you probably want to live to a hundred. And why wouldn't you want to live a super-long life, if you could remain in good health? You'd get to meet your great-grandkids, try out space travel and the teleporter, and gross out all your descendants by having noisy old-person sex. Comedian Ariane Sherine has always been determined to live into her hundreds, but never knew how. With so much conflicting and confusing health information out there, she didn't have a clue where to start until she met David Conrad, a public health expert, who helped her to weigh up all the research and evidence and explained exactly what to do to live a long and healthy life. And together, they've decided to tell you how to live to a hundred too. This book has all the facts, stats, inappropriate jokes and shameless puns you could ever need to make it to your eleventh decade. The evidence is given for a hundred factors that affect life expectancy - everything from green tea to gardening, sex to sweeteners. And celebrities weigh in with their own thoughts too, so you'll find contributions from Derren Brown, Richard Osman, Lou Sanders, Charlie Brooker, Konnie Huq, Robin Ince, Jeremy Vine, Clive Anderson and many more.
